I glance up from my monitor showing atmospheric simulations
I see evening sunlight streaming through
smoky sky scattered blue
Perhaps I have played with these models too long
They leak into my interpretation of mundane
Sunlight is composed of photons flung out after nuclear fusion in the sun
Jacchia-Roberts density model is irrelevant to rapidity of photonic speed
Assume refractive index n = 1.0003
Light speed reduction from vacuum to air by 90 km/s
Merely a 3/10,000 reduction of its total speed
Most brains with eyes don’t ponder this sight
The sky is blue with no clouds, so people say
A mundane statement of an accepted ordinary reality
